How to achieve asymmetric collective range for speed helis?

I am trying to achieve a collective range of +16°/-10° pitch at high/low collective stick with 0° pitch at center stick. I can achieve this by several ways, but I am trying to figure out which way is best.

One way is to set the collective range on the Spirit software so I get +16°/0°/-16° at high/mid/low stick and then adjust the pitch curve in the radio 0%-50%-100% to something like 21%-50%-100%

Another way is to adjust the "Servo Travel Correction" on the Spirit software so I get less travel at low collective stick.

I do not know how either method would affect the overall "resolution" and/or cyclic range deflection asymmetry.

Hello,

the first method is correct.
Usage of Servo Travel Correction is not a proper way, because it is not an assymetry of mechanics.
So configuring it in your radio is right.
